Refrigerators Samsung No Frost are famous for their reliability and convenience, but even they require correct temperature settings for long service life and food safety. Many users mistakenly believe that the factory settings are universal - however, the optimal values depend on the workload of the chambers, the indoor climate, and even the type of stored products. In this article, we will look at how to accurately regulate the temperature in the refrigerator and freezer compartments, avoid common mistakes and save energy without compromising food freshness.
The system No Frost eliminates manual defrosting, but does not relieve you of the need to control the microclimate inside. For example, too low a temperature in the main chamber leads to icing of food at the back wall, and a high temperature leads to rapid spoilage of meat and dairy products. We will analyze in detail which buttons to press on the control panel (depending on the model), how to reset the settings to factory settings, and what to do if the refrigerator does not maintain the set mode.
We will pay special attention to models with Twin Cooling Plus and Digital Inverter Compressor —their settings have nuances that are not written about in the standard instructions. You will also learn how to check the accuracy of the built-in thermometer readings and when to contact a service center.
Why it is important to correctly set the temperature in No Frost
The system No Frost works on the principle of forced circulation of cold air, which prevents the formation of frost. However, this does not mean that you can set any mode and forget about it. Incorrect settings lead to:
- 🔋 Increased energy consumption — the compressor operates in increased mode if the temperature is too high.
- ❄️ Icing products —at minus values in the refrigerator compartment (yes, this is possible!).
- 🦠 Rapid spoilage of food —at +8°C and above, bacteria actively multiply in meat and fish.
- 💧 Condensation on the walls —if the temperature difference between the chambers is too great.
The manufacturer Samsung recommends maintaining it in the refrigerator compartment from +1°C to +5°Cand in the freezer - from −18°C to −20°C. But these values are averaged. For example, if you store a lot of fresh vegetables, +3...+4°C is optimal, and for semi-finished meat products -20...−22°C is better.
Another nuance is the indoor climate. In hot regions or in a kitchen with a stove, the refrigerator requires more cooling, so the factory setting (+3°C) may not be sufficient. The opposite situation is in winter: if the kitchen is cool, the compressor will turn on less often, and the temperature in the chamber can rise to +6...+7°C.
Where is the temperature regulator located: types of control panels
In refrigerators Samsung No Frost there are three types of control panels: mechanical (rotary knobs), electronic (touch buttons) and display with touchscreen. The location of the regulators depends on the model and year of manufacture:
- 🔄 Mechanical panel —usually inside the refrigerator compartment on the top or side wall (models before 2018, for example, RL38 or RB37).
- 🖥️ Electronic panel with buttons —on the outside of the door or on top (series RT, RS 2019–2022).
- 📱 Display with touchscreen —in premium models (Bespoke, Family Hub) on the door facade.
To find the regulator, inspect:
- The top of the refrigerator compartment (under the ceiling lamp).
- The right side wall inside the main chamber.
- The outer panel on the door (if a model with a display).
In models with Twin Cooling Plus (two independent cooling systems), the temperature settings for the refrigerator and freezer compartments are separate. This means that you can set, for example, +2°C in the main chamber and. −24°C in the freezer - without mutual influence.
Step-by-step instructions: how to set the temperature
The setting algorithm depends on the type of panel. Let's consider each option in detail.
1. Mechanical regulator (rotary knob)
In old ones. models Samsung No Frost the temperature is regulated by a physical knob with divisions from 1 to 7 (sometimes up to 9). The rule applies here: the higher the number, the colder it is. data-i="102">the higher the number, the colder
- Refrigerator compartment:
3–4(corresponds to +3...+5°C). - Freezer compartment:
5–6(−18…−20°C).
☑️ Setting the mechanical regulator
⚠️ Attention: In some models (for example, SR-20**) the handle has a reverse gradation - 1 means maximum cold! Please check this in the instructions!
2. Electronic panel with buttons
In refrigerators with push-button control (series RT, RS), the temperature is set as follows:
- Find the button
Fridge(for the refrigerator compartment) orFreezer(for freezer). - Press
+/−to change the value. The range is usually from +1°C to +7°C for the refrigerator compartment and from −14°C to −25°C for the freezer. - Confirm your choice button
Setor wait for automatic saving (after 5 seconds).
Example path in the menu for the model RT38K6030SL:
Press [Freezer] → use the "+/−" buttons to set −19°C → press [Set]
Press [Fridge] → use the "+/−" buttons to set +4°C → press [Set]
3. Touch display (Bespoke, Family Hub models)
In modern refrigerators with a display, the setting is intuitive:
- Touch the ⚙️ icon
SettingsorTemp Control. - Select a camera (
FridgeorFreezer). - Swipe up/down or tap on "+/−" to set the value.
- Press
Saveor wait for automatic application.
How to reset the settings to factory settings?
In models with a display, hold down the ⚙️ icon for 5 seconds. In push-button models, press [Fridge] + [Freezer] simultaneously and hold. 3 seconds.
⚠️ Attention: After changing the temperature, wait minimum 6 hoursbefore checking the result. The compressor needs time to stabilize.
Optimal temperatures for different products
There are no universal values - it all depends on what you are storing. The table below provides recommendations for popular product categories:
| Product type | Refrigerator compartment (°C) | Freezer compartment (°C) | Notes |
|---|---|---|---|
| Fresh meat/fish | +1…+2 | −18…−20 | At +3°C and above, shelf life is reduced by 30% |
| Dairy products | +2…+4 | −16…−18 | Cottage cheese and sour cream spoil faster at +5°C |
| Vegetables/fruits | +4…+6 | −12…−14 | Tropical fruits (bananas, pineapples) are not stored in the cold |
| Ready meals | +3…+5 | −18 | Soups and sauces are best cooled to +2°C |
| Ice cream | — | −22…−24 | When −18°C can thaw |
If your refrigerator has a zone FlexZone (for example, in models RF23**), it can be adjusted separately:
- 🥩 Meat mode: +1°C (for raw products).
- 🧀 Cheese mode: +3°C (for hard cheeses).
- 🍷 Wine mode: +10...+12°C (if the zone supports).
Typical mistakes when setting the temperature
Even experienced users sometimes make mistakes that lead to food spoilage or breakdowns. Let's look at the most common ones:
- Ignoring external conditions. If the kitchen is +30°C and the refrigerator is located next to the stove, the factory +4°C may not be enough. In this case, temporarily reduce the temperature by 1–2 degrees.
- Frequent settings changes. The compressor takes time to adapt. If you change the temperature every day, this leads to increased wear.
- Overloading of chambers. When food is packed tightly, air circulation is disrupted and the sensors show incorrect values. Leave gaps between packages!
- Using external thermometers without checking. A household thermometer can have an error of up to ±2°C. Before setting up the refrigerator, test it in a glass with ice (it should show 0°C).
Another mistake - ignore the "Vacation" mode. If you are leaving for a long time, activate this function (if available in the model). It maintains +15°C in the refrigerator compartment, preventing mold, but saving energy.
⚠️ Attention: If after changing the settings of the refrigerator does not cool to the set temperaturecheck:
- The tightness of the doors (possibly the seal worn out).
- Clogged ventilation holes (in models No Frost they are located on the back wall).
- Operation of sensors (if a breakdown occurs, an error may appear on the display, for example,
22Eor25E).
How to save energy without damaging food
The refrigerator Samsung No Frost consumes up to 30% of all electricity in the house. But there are ways to reduce costs:
- 🌡️ Optimize temperature: every degree below −18°C in the freezer increases consumption by 5-7%.
- 🔌 Turn off "Quick Freezing" (
Power Freeze) after use. It speeds up cooling, but spends 20% more energy. - 🧊 Thaw ice in the freezer with a thickness of more than 5 mm - it worsens heat transfer.
- 🌿 Do not place hot dishes - this makes the compressor operates in enhanced mode.
In models with Digital Inverter Compressor (for example, RB37J5**) there is a mode Eco. It automatically selects a balance between cooling and energy consumption, analyzing the frequency of door openings and the load on the chambers. It is activated like this:
Click [Eco Mode] on the panel → wait for the signal → the mode is activatedAnother secret - correct placement of products:
- Store on the top shelves (the warmest place) sauces, drinks, eggs.
- On the middle ones - dairy products, ready meals.
- On the bottom (the coldest) - meat, fish.
- In the door - only products resistant to temperature changes (butter, ketchup).
What to do if the refrigerator does not hold the temperature
If, after setting, the temperature in the chambers does not correspond to the set temperature, the reasons may be different - from a malfunction of the sensor to a freon leak. Let's consider typical situations:
| Symptom | Possible cause | Solution |
|---|---|---|
| Temperature above the set temperature | Worn door seal | Check the tightness with a sheet of paper - if it pulls out easily, replace the seal |
| The freezer is working, the refrigerator compartment is not | The capillary tube is clogged | Needs cleaning or replacement (contact your service) |
| The compressor works without stopping | Thermostat malfunction | Replace the temperature sensor (error code usually 22E) |
| Frosting of the rear wall | System malfunction No Frost | Check the operation of the fan and defrosting heating element |
If the refrigerator displays an error on the display (for example, 40E or 85E), you can decipher it in the instructions or on the website SamsungSome codes (for example, 22E) indicate a sensor failure, others (for example, 41E) indicate problems with defrosting.
How to reset the error on the display?
In most models, the error is reset by holding the [Freezer] + [Fridge] button for 10 seconds. If the error appears again, it is required. repair.
⚠️ Attention: If the refrigerator Samsung No Frost stops cooling, but the compressor is humming, do not try to disassemble it yourselfin systems with freon R-600a or R-134a special equipment is required for refilling.
FAQ: Frequently asked questions about setting the temperature
🔹 Why is it −24°C in the freezer, but the food is not frozen?
The temperature sensor is probably faulty or the air circulation is impaired. Check:
- If the ventilation holes are clogged with ice or food.
- Is the fan working (it should stop when the door is open).
- Are there any errors on the display? (codes
25E,26Eindicate problems with sensors).
If everything is in order, but the freezer is not freezing, call a technician to diagnose the compressor.
🔹 Is it possible to set different temperatures in the upper and lower parts of the refrigerator compartment?
In Most models Samsung No Frost —no, since the cooling is uniform. However, refrigerators with Twin Cooling Plus (for example, RF23HCEDBSR) have separate controls for the upper and lower zones. Also, some models support FlexZone —a compartment with independent settings.
🔹 How often should you check the temperature?
Once a month is enough if:
- The refrigerator is not overloaded.
- Doors open no more than 10-15 times a day.
- No external ones heat sources (stove, battery) nearby.
In the hot season or during intensive use, check once every 2 weeks.
🔹 Why did the refrigerator not restore the temperature after the power went out?
If the power outage was long (more than 4 hours), the food could heat up, and the compressor needs until 24 hours to restore the mode. The following will help speed up the process:
- Activation of the mode
Power Cool(if available in the model). - Reducing the loading of the chambers (remove some of the products).
- Checking the seals - after a power surge they could deformed.
🔹 Is it possible to turn off No Frost and switch the refrigerator to normal mode?
No, the system No Frost is a design feature of the model, and it cannot be disabled programmatically.
- Reduce fan intensity (some models have a setting
Air Flow). - Check seals and vents more often to avoid icing.
If you are not satisfied with the operation No Frost, consider buying a refrigerator with a drip system (Direct Cool).
